My invention relates generally to railway car end construction, and moreparticularly to the car end wall. Y

In railway cars, and particularly those designed for and used in freightservice, the end portions of the car body, and particularly the endwalls, are subjected to severe stresses and strains' resulting fromshocks and vibrations, and by reason of the sudden starting and stoppingof the cars and the shifting of the load or contents, of the cars whilethe latter are in transit.

I propose to construct a car end wall from sections of sheet metal, thesame being provided with pressed ribs or corrugations arranged so as tmaterially strengthen and stiften the end wall and the anels thereof,thereby providing a construction which will eectually resist internallyor externally applied pressure and the resulting stresses and strains. y

The principal object of my invention is to construct a car end wallfroma plurality of sections of material, preferably sheet metal, eachsection being reinforced and stiffened by means of ribs or corrugationspressed in the sheet metal, thus providing a comparatively simple,inexpensive vconstruction which can 'be readily utilized in connectionwith an Ordinary car underframe and superstructure, and which end wall fr -plate will be eective in resisting all stresses resulting from,shifting loads, ordiparatively narrow. The main sections 1 and.

2 are preferably formed of lapproximately rectangular pieces of sheetmetal, and the upper edge of the top section 2 is shaped so as toconform with the shape of the car roof.

The side and lower edges o f the section 1 and the side and upper edgesof the section 2 are bent at right angles to the plane occupied by themain body portion of said sections in Order to form marginal flanges l,whereby the end wall or plate may be readily attached to the framey ofthe car body.

The horizontally disposed section 3 is, as heretofore stated,comparatively narrow and its ends are bent rearwardly, as designated by5 to correspond with the bent side edges of the sections l and 2, andare arranged for attachment to frame portions of the car body. -Thelower edge of the section 2 overlies the upper edge of the intermediate'section 3, and the lower edge of said interribs or corrugations 7, thesame being pressed from the material of which said sections are formed,and said ribs or corrugations are preferably deepest at their centersand gradually decrease in depth toward their ends. These ribs orcorrugations are preferably arranged at equal distances apart 'and theseries of ribs or corrugations in one of Vso the plates are preferablyin alinement with the corresponding ribs and corrugations of the otherplate.v .4

Formed in the lower plate 1 adjacent to the outermost pair of ribs orcorrugations are ribs or corrugations 8 which converge upwardly, andthese ribs or corrugations are preferably deepest at their centers andgradually decrease in depth toward their ends.

Formed in the upper section 2 and preferably in alinement with theconverging ribs or corrugations 8 are corresponding ribs or corrugations9 which converge upwardly, and these last mentioned ribs or corrugationsare formed like the other ribs or corrugations,.-that is, they aredeepest at their centers and gradually decrease in depth toward theirends.

Formed in the intermediate narrow section 3 and extending practicallythe entire length thereof isV a rib or corrugation l() which ispreferably deepest at its central portion, and which gradually decreasesin depth toward its ends. The intermediate section 3 which is stiifenedand reinforced by the rib or c orrugation 10 is rigidly fixed to thecorresponding edges of the main sections 1 and 2, and thus forms a verystrong and rigid reinforcement for the end wall or plate at a pointapproximately midway between its upper and lower edges, and said endwall or plate v4is further reinforced and stiifened by the verticallydisposed ribss or corrugations 7 and the inclined ribs or corrugations8. Such construction provides a car end wall or plate which is verystrong and durable and which is particularly effective against stressestending to distort said end Wall.

My improved construction effects a considerable saving in the initialcost of construction ofthe car end walls in the cost of repairs and byforming the entire end in sections the latter can be much more easilyhandled by the workmen during the formation of the ribs or corrugationsand in the assembling or repairing of the structure than where an endplate or wall is formed in a single large piece. f

The ribs or corrugations are arranged and disposed so as to stifen andreinforce the en d wall to a maximum degree, and the impact of allinternallyan'd externally applied shocks or blows and all servicestrains and vibrations will be transmitedv directly to the' underfrainesills and plates forming a part of the car body frame.

It will be readily understood that minor changes in thesize, form andconstruction of the various parts of my improved car end can be made andsubstituted for those herein shown and described without departing fromthe spirit of my invention, the scope of which is set forth1ntheappended claims.

I claim:

1. As a new article of manufacture a car end comprising a comparativelywide upper section, a comparatively wide lower section, and acomparatively narrow intermediate section, the`upper edge of whichintermediate section lies inside and is fixed to the lower edge of theupper section, the lower edge of which intermediate'section lies outsideand is liXed to the upper edge of the lower section, and saidintermediate section having pressed therein a longitudinally reinforcingand sti'ening rib or corrugation, thereby. forming a transverselydisposed reinforcement at a point substantially midway between the upperand lower edges of the car end.

2. As a new article of manufacture, a car end-comprising a comparativelywide lower section, a comparatively wide upper section, a comparativelynarrow intermediate section, the lower edge of which upper sectionoverlies the upper edge of the intermediate section, the lower edge ofwhich intermediate section overlies the upper edge of thel lowersection, and each of which sections has pressed therein a reinforcingand stiffening rib or corrugation.

As a new article of manufacture, a car end comprising a comparativelywide corrugated lower section, a comparatively wide corrugated uppersection, a comparatively narrow corrugated intermediate section, the

lower edge of which upper section overlies the upper edge of theintermediate section, and the lower edge of which intermediate sectionoverlies the upper edge of the lower section.

gated sections of sheet metal, the corrugation of one section lyingapproximately at right angles to the corrugation of the other lsections,the lines of separation between said sections being horizontallydisposed and the sections being arranged so that a watershed is providedon the exterior of the car end forming a protection against the entranceof water and dust into thecar through the joints between said sections.v 5. A car end comprising a series of sections of sheet metal, each ofwhich is provided with a pressed stiffening rib or corrugation, the ribor corrugation of the intermediate section lying substantially at rightangles to the ribs or corrugations of the other sections, the jointsbetween which said sections are horizontally disposed, and said sectionsbeing arranged so that a watershed is provided on the exterior of thecar end forming a protection against the entrance of water and dust intothe carv upper panel, a lower panel, and an intermediate panelconnecting the two, said upper and lower panels being provided withtransversely extending corrugutions und with 0bliquely extendingcorrugntions, the transvereely extending corrugutions of the upper panelbeing disposed in alinexnent with the transversely extendingeorrugutions of the lower panel, and the obliquely extendingcorrugations of the upper panel being disposed in nlinenient withtheololquely eX- tending eorrugzltione of the lower panel, and theintermediate panel being provided with u longitudinally extendingeorrgzttion tel i lninzlting adjacent its extremities ind adapted toreceive moments transn'ntted by the corrugatlons ot the upper mid lowerpanels.
